CVE-2011-4077

CVE-2011-4077 is a Linux kernel XFS-related vulnerability described in the provided documents as a buffer overflow in the xfs_readlink function (fs/xfs/xfs_vnodeops.c) when CONFIG_XFS_DEBUG is disabled. The issue affects Linux kernel 2.6 with XFS, allowing a local attacker to cause memory corrupt...

CVE-2012-3511

The CVE-2012-3511 entry maps to the Linux kernel issue in mm/madvise.c: madvise_remove contains race conditions that can be exploited locally to trigger use-after-free and kernel crash, resulting in denial of service via munmap or close. Affected lineage includes kernels before 3.4.5; patches add...

CVE-2011-4086

The CVE-2011-4086 vulnerability affects the Linux kernel prior to 3.3.1, where journal_unmap_buffer in fs/jbd2/transaction.c mishandles _Delay and _Unwritten journal buffer head states. This can crash the system (local DoS) when an ext4 filesystem is mounted with a journal. Remediation: upgrade t...

CVE-2012-1097

CVE-2012-1097 affects the Linux kernel before 3.2.10, where the regset (register set) path mishandles absence of .get/.set methods. This can allow a local attacker to trigger a NULL pointer dereference via PTRACE_GETREGSET or PTRACE_SETREGSET, possibly causing denial of service or other impact. R...

CVE-2012-0207

CVE-2012-0207 affects the Linux kernel before 3.2.1, where igmp_heard_query in net/ipv4/igmp.c can be triggered by IGMP packets to cause a divide-by-zero leading to a kernel panic (DoS). The vulnerability is addressed in Linux 3.2.1 (as per ChangeLog-3.2.1). Connected advisories/Nessus entries re...

CVE-2012-4508

CVE-2012-4508 is a race condition in the Linux kernel's ext4 extents handling (fs/ext4/extents.c) that, before version 3.4.16, allows a local unprivileged user to read data from a deleted file by reading an extent that isn’t properly marked uninitialized. The issue is fixed in the 3.4.16 update (...

CVE-2012-2123

CVE-2012-2123 affects the Linux kernel up to version 3.3.3, where cap_bprm_set_creds in security/commoncap.c mishandles file-system capabilities (fcaps) for implementing a privileged executable. This can let local users bypass personality restrictions via a crafted application, demonstrated by an...

CVE-2012-0957

CVE-2012-0957 affects the Linux kernel prior to 3.4.16. The override_release function in kernel/sys.c can let a local user leak kernel stack memory by calling uname with the UNAME26 personality. This is a local-privilege scenario; no remote vector is described in the provided documents. Affected ...

CVE-2012-0045

CVE-2012-0045 relates to the Linux kernel KVM 32-bit syscall emulation. A flaw in arch/x86/kvm/emulate.c where the 0f05 (syscall) opcode is not handled correctly allows a user in a 32-bit guest to crash the guest OS (denial of service).
